Appncaaon'aled May 2, 1917. sel-iai No. 166,030.

This invention relates to metallic windows and has forone of its objects to provire a novel metal window sash in which yeach of the barsvor rails thereof is made from a single piece of sheet metal folded into the lrequired shape and in such a way that the edges ofthe sheet are positively locked together, and in which the bars or rails of the sash are connected at their corners by an improved corner plate which simplifies the operation of manufacture and assembling. '1

Other objects of the invention are to improve metal window sashes and window frames in the particulars hereinafter more fully Vset forth.

In order to give an understanding of my invention I have illustrated in the drawings a selected embodiment thereof which will now be described, after which the novel features thereof will be pointed out in the appended claims. Y

Fig. 1 is a vertical sectional view through a window frame and window sash made in accordance with my invention, the section extending from the top of the window frame to a point just below the top rail of the lower sash, parts of the. sash and frame being broken out;

Fig. 2 is a section through the jamb of the window frame and the side lrail of the sash; p

Fig. 3 is a. corner View of the sash and frame;

Fig. 4 is a perspective sectional view of a corner of the window sash showing the corner. plate. in operative position; y

Fig. 5 is a view showing the corner plate detached from the ends of the bars of the window sash;

Fig. 6 is a section on the line 6 6, Fig. 5.

In Fig. 1 which is a vertical section through a metal window frame embodying my invention, 1 indicates generally the window frame comprising the top or head portion 2, the base or sill portion (not shown) and the sides or jambs 3. The upper sash is indicated generally at 4 and the-lower 6 indicates the glass for the the glassfor the lower sash at 5. upper sash and 7 slash.

Each of the sashes is made of four rails or bars comprising the two side rails 'or stilesv8,`the top rail 9 r'and the bottom rail 10,. and these four bars or rails ofl eachk sash are connected at the 'corners' by corner plates of novel construction, thus ycompleting the'sash.

One feature of my invention relates to making each of the yrails of each sash from a single sheet of metal whichis benty into the desired shape and is formed in such a way that the meeting edgesl of the sheet are positively locked together. The shape into which each of these bars or railsis bent is seen best in Fig. 1. Referring, for instance, to the top rail 9 of the upper sash,

this is bent into shape from a sheet thereby to form the two side faces 11, theback side 12 andthe inner glass-receiving side having a groove to receive the glass` 6. This inner side is formed with the two suitably-shaped portions 18 and 14 which lgive the appearance of a molding. The portion 13 is bent inwardly at 15 to form one sideV of a glass-receiving groove, and then is bent laterallyy at 16 tov form thebottornl of the" groove. The edge of the portion 14 is also bent inwardly, as at 17, to form the other side of the glass-receiving groove. The sheet from which the upper rail 9 is formed will preferably have its edges locked together at the side of the groove, and this is herein accomplished by providing the portion 17 with the laterally-extending locking flange 18 and by extending the portion 16 and bending the extension 19 thereof around the flange 18 and vturning the edge 20 at right angles to the portion 16 so that it will overlie the side y17, the marginal edge of the portion 2O being received 1n a groove 21 rating in a direction transverse to the frame are also made of sheet metal bent into the proper shape.

-. of the rail.

A tubular member is thus formed from a v.piece of sheet metal in such a way that the V'sheet from which the rail 9 is made so as to present two ribs 22 on the upper face All of the rails of each sash may-'be madein this same way, although I will preferably. make the upper. rail 9 of the lower sash .with a flat upper surface, as shown at 23. When thus made each rail of the sash is provided with a glassreceiving groove into which the edge kof the glass is received. The four rails of each sash are secured together at their corners by a corner plate 24 o f'novel construction. This corner plate comprises a body portion having two extensions 25 that are adapted to overlie the side vfaces 1l ofthe adjoiningk bars and with two 'fingers 26'that are adapted to enter the hollow ribs or flanges 22. These flanges 22 are so shaped that the yinner face 28v thereof is in the same plane' as the face lll of the rail, the outer face 27 being offset slightly and the twofaces 26 and 27 are spaced apartsufficiently to receive the fin er 2 6.` The glass-receiving edge of each sas is mitered, as shown at 29. In assembling the rails, the fingers 26V of the corner plates are inserted into the space between the walls 27 `and 28 of the flanges 22, and the extensions 25 thereof are arranged to overlie thefaces l1 of the rails. The corner plates are secured to the Vrails by attaching screws 30 which extend through apertures 31 and 32 formed inthe corner plate and faces-1 1 of the rail, respectively. The corner plate is alsov provided with theangular extension 33 which overlies and covers'theV joint between the mitered edges 29. .advantage of this is that the Vextension 33 The .'makes al proper finish to the corner so that a finished sash is produced, even though the mitered edges29 do not fit accurately. With this construction, therefore,'it is not necessary to :take such pains toget an exactfit vbetween the mitered edges 29 as would be required if the finishing extension 33 were not present. It will of course be understood `that the glass is to be placed in the glass receiving grooves as therails of the sash are lbeing assembled. A corner plate of the above nature wouldv be used von -both sides of the ysash at'each corner, thus requiring 'eight cornerV platesvfor each sash. If de- Yslred the two `corner plates` at each corner may be connected by the bridge piece 44 4as seen in Fig. 6. The sides, top and bottom of the window rIhe top or head 2 of thewindow frame is formed so as to present the-two .guiding ribs 34 between which the are received. The jamb of the window Vframe is bent torpr'esent the outwardly-extending rib 34 and the inwardly-extendingl l grooves 35 and 36. These grooves receive parting strips 37 which are made of sheet Vmetal. Each parting strip is `made from a strip of sheet metal which is bent back on itself centrallyand one edge 38 of whichV is vreceived in the groove or 36, and the other edge39 of which is bent back parallel to the body thereby to form with the body a groove 40. The groove 40 of eachparting strip is adapted to receive and form a guide rside vand top and bottom rails, each rail being formedv from a single sheet kof metal bent into the required shape to form a glassreceiving groove, both sides of which are -formed from bends in said sheet metal, the meeting edges of each sheet being situated at one side of the groove and being posiment in either a direction parallel to the plane of theV sash or in a direction transverse to-said plane.

2. A window sash comprising connected Atively interlocked against separating moveside and top and bottomrails, each rail j being formed from ay single sheet of metal bent into-the required shape to form a glassreceiving groove, both sides ofy which are formed by the sheet metal, the meeting edges of each sheet being. situated at'the side of the groove and being positivelyinterlocked against separating movement in either one oftwo directionsat right angles to each other.vr

3. A metal window sash comprising side,

top and bottom rails, each formed from a sheet of metal bent into the` desired shape, and corner plates for securing said rails together, each `corner plate having an extension overlying'the .outer 'face of Aeach rail, and a D 'finger which overlies the inner face, and means securing the corner plate'to the rail.

4. A vmetal-sash comprising side, top and bottom rails, each being formed of a piece of sheet metal bent in to the desiredV shape and provided with a glass-receiving groove,

each rail being mitered at both ends on its Vglass-receiving edge, and corner plates for connecting said rails, each corner plate having a downwardly and inwardly-directed extensionwhich is situated on the outside of and overlies the meeting miterededges of two rails. In testimony whereof, I have signed my namefto this specification'.
